A vacuum seal container comprises a cylindrical container body having a peripheral seal extending therearound and a lid including an outer skirt for engaging the seal. The skirt defines an access port for communication with a vacuum-generating source. The lid further includes seating nodes which seat the lid in a raised position to form an interior air passageway for air evacuation. At reaching a threshold pressure difference between the inside and outside of the container, the seating nodes and the sidewall deform to lower the lid which blocks the interior air passageway to form a vacuum seal.

A vacuum seal container comprising: a container body defining an outer body surface; a peripheral seal supported on the outer surface of the container body; a container lid including a downwardly depending skirt having an inner skirt surface for engaging the peripheral seal, the inner skirt surface

A vacuum seal container comprising: a container body defining an outer body surface; a peripheral seal supported on the outer surface of the container body; a container lid including a downwardly depending skirt having an inner skirt surface for engaging the peripheral seal, the inner skirt surface to oppose and to be spaced slightly outwardly from the outer body surface such that the inner and outer surfaces define a space therebetween, the skirt further defining an access port for externally communicating with a means for evacuating air from the interior of the container body; and means for seating the lid on the container body in a raised and a lowered position, the seating means to seat the lid in a raised position being such that the access port is positioned above the peripheral seal when the pressure difference between the interior and exterior of the container is below a threshold level, the access port and the space between the outer body surface and the inner skirt surface forming an air passageway to the interior of the container body for evacuating air from within, and the seating means to seat the lid in a lowered position being such that the peripheral seal is positioned above the access port when the pressure difference reaches the threshold level, the peripheral seal blocking the air-passageway between the access port and the interior of the container body so as to substantially form a vacuum seal.
